added (and stripped) a simple C/C++ preprocessor (written in Lua), so the stringifier can handle the #include directive,

and embed the included files directly in the stringified files.
We need this, because we start sharing struct definitions and code between C/C++ and OpenCL (and potentially other languages)
preprocessor is from http://github.com/willsteel/lcpp
